Ulcers and Skin Damages (TI P2) Flashcards
Pressure Ulcers
also called pressure injury
localized injury to skin and/or underlying tissue
What do pressure ulcers result from?
prolonged pressure or pressure in combination with shearing forces
can be related to medical or other devices
Where are pressure ulcers most commonly found?
over bony prominences, sacrum, heels
Describe the pathophysiology of pressure ulcer development
pressure over a prolonged period of time will stop capillary flow to the tissues, which will deprive tissues of oxygen and nutrients, and will eventually lead to cell death or tissue necrosis
What are influencing factors to pressure ulcers?
pressure intensity
pressure duration
tissue tolerance factors
shearing forces
moisture
What could affect the ability of a tissue to tolerate the pressure (tissue tolerance factors)?
nutrition
perfusion
co-morbidities
condition of soft tissue
What are risk factors to pressure ulcers?
advanced age
anemia
diabetes
elevated body temperature
friction
immobility
impaired circulation
incontinence
low diastolic BP
mental deterioration
neurological disorders
obesity
pain
prolonged surgery
vascular disease
What are clinical manifestations of pressure ulcers?
depends of extent of tissue
staged/categorized based on visible or palpable tissue in the ulcer bed
presence of slough or eschar may prevent staging until it is removed
Suspected Deep Tissue Injury
purple or maroon localized area of discolored intact skin or blood-filled blister
indicates damage of underlying soft tissue from pressure and/or shear
may be preceded by tissue that is painful, firm, mushy, boggy
When assessing patients with darker skin, you should…
look for areas of the skin that are darker than the surrounding skin; may appear purple, brown, or blue
When assessing skin temperature with your hand, the ulceration should feel _____ initially, then become _____ with time
warm; cooler
Boggy or edematous tissue may indicate…
stage 1 pressure ulcer
Stage 1 Pressure Ulcer
intact skin, non-blanchable redness of localized area
common over bony prominence
may be painful, firm, soft, warmer, or cooler as compared to adjacent tissue
Stage 2 Pressure Ulcer
partial-thickness loss of dermis
shallow open ulcer with red/pink wound bed
may also present as an intact or ruptured serum-filled blister
Stage 3 Pressure Ulcer
full-thickness loss
subcutaneous tissue may be visible
presents as deep crater (depth varies on location)
